Probably because they introduced it afterwards, and thus to not break compatibility with all other apps they tried to make it transparent to the developer. Except it's not. I get that Apple is going into the direction of forbidding local LAN communication because they want you to implement Homekit protocol in the hardware, except that is a pain, requires certification of the hardware and requires a physical chip inside the hardware.
